II. A Closed Hyperbolic Model Fagundes, Helio V. Abstract This is the second of two papers developing a conjecture that might solve the quasar redshift controversy. The quasar-galaxy or quasar-quasar associations with discordant redshifts reported by Arp and others would be explained as the effect of multiple image production in a cosmological model with nontrivial space topology. The model here explored has the same local metric as Friedmann's open model, but the latter's infinite space is replaced by a closed space, constructed as usual from a polyhedron with faces pairwise identified. The results exhibit, semiquantitatively, some of the characteristics of the mentioned associations, and are suggestive of other effects such as an inhomogeneous distribution of QSO images on the sky. But no actual fitting of data is attempted, for these are too rich and varied, and probably will require a more complex topology for their explanation than the one used here. So the present model will be seen as a prototype for future developments in this direction. A possible connection with the ideas of small universe of Gott and Ellis is hinted at.
